be worth doing和be worth to be done的区别

没有be
worth
to
be
done的说法，只有be
worth
doing和be
worthy
to
be
done的说法。
worth是介系词，后面只能跟动名词的主动形式，但表示被动姿搏桥的意义，如：
The
book
is
worth
reading.
If
something
is
worth
doing,
it's
worth
doing
well.
worthy是形容词，这个词的后面要跟介系词of，of之后才要银颂跟动名词的被动式，或者直接跟动名词的被动式。如：
The
book
is
worthy
of
being
read.
If
something
is
worthy
to
be
done,
it's
worth
to
be
done
well.
另外，还有一个字叫做worthwhile，也是形容词，它可以作表语，后面可以用动词不定式和迹猛动名词，作其真正的主语：
It's
worthwhile
to
read
the
book.
If
it's
worthwhile
doing
something,
it's
worthwhile
doing
it
well.
